Symptoms
- vProxy 裝置無法使用 nsrvproxy_mgmt 公用程式進行升級。
- vProxy /opt/emc/vproxy/runtime/logs/vrapid/vrapid-engine.log
./opt/emc/vproxy/runtime/logs/vrapid/vrapid-engine.log:YYYY-MM-DDTHH:MM:SSZ ERROR: Unable to lookup IP address for host "myNWServername.abc.com", err=lookup myNWServername.abc.com on ##.###.##.###:53: dial udp ##.###.##.###:53: connect: network is unreachable ./opt/emc/vproxy/runtime/logs/vrapid/vrapid-engine.log:2023-09-23THH:MM:SSZ ERROR: Unable to lookup IP address for host "myNWServername.abc.com", err=lookup myNWServername.abc.com on ##.###.##.###:53: dial udp ##.###.##.###:53: connect: network is unreachable ./opt/emc/vproxy/runtime/logs/vrapid/vrapid-engine.log:2023-09-25THH:MM:SSZ ERROR: Unable to lookup IP address for host "myNWServername.abc.com", err=lookup myNWServername.abc.com on ##.###.##.###:53: dial udp ##.###.##.###:53: connect: network is unreachable
Cause
當 vProxy 主機的 IP 位址指派給多個虛擬機器 (VM) 時,可能會發生此問題。NetWorker vProxy 執行階段記錄 dipict dial udp ##.###.##.###:53: connect: network is unreachable.
NetWorker vProxy 可能不會顯示 IP 衝突錯誤。有可能顯示為「無法判斷網路介面」或「無法連線網路」RRR。
Resolution
選項 1:
DNS 伺服器層級故障診斷
檢查 DNS 伺服器的 vProxy IP 位址和主機名稱,以找出相同 IP 的重複主機名稱。選項 2:
網路層級故障診斷:
1.關閉vProxy_HostA
2.在 NW 伺服器 CLI 上執行下列命令:
ping -a IP_of_vProxy_Host
nslookup IP_of_vProxy_Host
nslookup vProxy_Host
3.修正重複的 IP 衝突,然後前往升級 NetWorker vProxy 裝置。
